Nishi vs the Field

Deep Research and Answer Engines — mechanically measured, liar-killed, sovereign.

Nishi vs Perplexity and DeepResearcher and Tongyi DeepResearch and deep-searcher

How this is scored. Every Nishi cell is measured: the generator reads the real organ source on disk and requires the implementing symbol to exist (no self-grading). Competitor cells record documented capability presence. Best=leads this axis, Yes=present, Part=partial, No=absent. This is capability presence, not depth or scale: the majors lead on index size and neural ranking. Nishi's genuine exceeds are the sovereignty / neutrality / determinism axes.

A 2-shot surface-form variant won +104 on the single-gold standalone bench but did NOT transfer to the multi-alias on-protocol metric (SQuAD 427 vs 510) and was reverted (confirmed by nx_reader_ruler_adversary_gate 9/9). Evidence-grounded: SQuAD human F1 86.8 / LR-baseline 51.0 per fetched primary source arxiv:1606.05250 (nx_evidence_verify_gate 7/7); published neural SOTA (approx 900 permille) still leads

Honest verdict. Nishi has broad, sovereign search-engine presence — a real organ behind every core ranking and crawl axis, built bits-up in one language. It is not yet a scale or neural-ranking rival: the majors lead on index size (billions to trillions vs a Common-Crawl-seeded slice) and trained rerankers. Nishi's genuine exceeds are structural — owning the whole stack, neutrality by construction, and a zero-JS integer-deterministic result page. The climb is a bigger index and a trained reranker.
